“The risk of infection for the population is zero. This virus is very contagious for animals, but not for humans. We try to prevent psychosis from developing as has already happened in the past: psychosis does more damage than virtus” . Like this Maurizio Ferri, veterinarian for the breaking latest news ASL and responsible for the scientific coordination of the Italian Society of Preventive Veterinary Medicine, invites you to calm down.
David Quammen: “Citizen health is a topic of national interest. No to pseudo-experts”
by Maurizio Molinari
“The succession of discoveries of H5 HPAI avian influenza outbreaks, as occurred in Lazio, but in recent weeks similar cases have also been registered in poultry farms in Northern Italy, should not worry the population: the foods in the food chain are not contaminated and it is highly unlikely that there could be a passage of the virus to man. What’s the real problem now? The disposal of the carcasses of dead animals that have been infected and of those that will have to be killed. Because it must be done with the utmost respect for biosecurity protocols “

The discovery of the avian flu outbreak in a non-commercial farm in Ostia a few kilometers from Rome emerged following the checks after an anomalous mortality of the animals was found. Brought to the laboratory, from a sample of birds, the zooprophylactic institute confirmed what was already a suspicion: it is avian influenza of subtype H5 Hpai. The extraordinary containment measures were immediately taken with the establishment of a protection area with a radius of 3 kilometers from the breeding site of the flu outbreak and a surveillance area with a radius of 10. All the farms in the area have been verified, while all vehicles and equipment used to transport poultry have been subjected to pest control. The whole area will remain off-limits for 21 days.

“It is important to close the surveillance area because this is precisely the most delicate phase: it is necessary to limit the radius of the outbreak as much as possible – Maurizio Ferri emphasizes – But I repeat, the infection found on the outskirts of Rome, also called avian plague, as well as the outbreaks found in farms both in Veneto and in Lombardy, it is highly pathogenic, but only for the species where it was found, i.e. it has a high rate of transmissibility and mortality for birds, not for humans. That is, in order for it to become dangerous it is necessary that there are conditions for a transmissibility between birds and humans. For example, a similar condition has been found in some small rural farms in Asia where the virus has replicated in humans, but we are talking about close cohabitations between humans and infected birds “.

But how do these viruses get to farms? “For example from migratory birds – explains Maurizio Ferri – this is why the biosecurity measures of livestock are important, to be effective they must provide for protection from both land animals and other species of birds. At the moment, however, there is no risk of transmission of the virus that remains confined to that species and our meats on the market are safe “.
